TRAVERSE-MOTION FOR SPINNING-MACHINES.

Application filed March 20, 1901. Serial No. 51.992. (No model.)

[0 all 70/1/0772, it may concern:

Be it known that I, OSCAR L. OWEN, a citizen of the UnitedStates, residing at Whitinsville, in the county of \Vorcester and State of Massachusetts, have invented anew and useful Improvement in Traverse-lllotions for Spinning-Machines, of which the following is a specification.

To secure the even wearing of the d rawingrolls of spinning-machines, the roving-guides controlling the passage of the roving through the drawingrolls are moved continuously parallel to the rear rolls to distribute the wear on the rolls.

The object of this invention is to change the limits of this traverse; and to this end the invention consists in the peculiar and novel construction whereby the limits of the traverse of the roving-guides are automatically varied, and the extent of the traverse may be varied, as will he more fully set forth hereinafter.

In my present invention I engage with a driving-worm two worm-gears, one of which has a greater number of teeth than the other.

- One of these gears rotates an eccentric acting on the fork of a lever. The opposite end of this lever connects with the fulcrum of the arm on which the roving-rod is secured, the lever being pivoted on a fixed fulcrum intermediate the ends. The other gear 0p crates a cam acting on the roving-supporting arm. By this arrangement the relations of the throw of the eccentric and the cam change at each revolution of the gears, one gaining a tooth or more on the other.

Figure 1 is a rear View of my improved traverse-motion. Fig. 2 is a transverse sectional view of the same, showing the relation of the parts to the drawing-rolls. Fig. 3 is a View, partly in section, of the forked lever, the actuating-arm, the eccentric actuating the lever, and the cam operating the arm.

Similar marks of reference indicate corresponding parts in all the figures.

In the drawings, a indicates the top rail of a spinning-machine on which the stands supporting the drawing-rolls are supported.

In the preferred form I operate the traversemotion by means of aworm b on the rear drawing-roll b, the set of drawing-rolls consisting of the rear drawing-roll b, the intermediate 11 the front roll b and the top rolls 1) b As the vertical distance between the rail a and the back drawing-roll b differs in spinning-ma chines made by different makers, I provide the standard a with a vertical slot and adjustably secure the post a by means of the screw a to the standard a. In the post a the stud a is secured nearthe upper end and the fulcrum -pin a near the lower end. On the stud a is journaled the sleeve 0 of the cam 0, preferably a heart-shaped cam. The worm-gear c is sooured to the sleeve 0 and engages with the worm Z). The worm-gear 0 which has preferably one tooth more or less than the wormgear 0 is provided with the eccentric c and is journaled on the sleeve 0. The eccentric 0 acts on the two arms of the fork d of the lever cl, which lever is supported on the fulcrum-pin a and is pivotally connected at its lower end with the lower end of the arm 6, the pins c e on which engage with the cam c. The upper end of the arm e has the slot 6 The slide e in the slot 6 is secured adjustably by the screw-stud e in the slot a of the bracket 6, secured to the traverse-rod e 011 which the roving-guides e a are supported.

When the traverse motion is in use, the rotation of the back drawing-roll b and the worm b imparts rotary motion to the wormgcars c and c and through the same to the eccentric c and the cam c, the relative positions of the cam and eccentric changing gradually by the difference in the number of teeth in the two gears; The eccentric c swings the lever d on the fulcrum-pin a the lower end of the lever moving the pivot supporting the arm 6 from side to side, while the heartshaped cam c swings the arm 6 and by the same imparts reciprocating motion to the traverse-rod 6 The continuous change of the position of the pivotal support of the arm 6 causes the arm to rock on the cam c and to move the upper endof the lever with the bracket 6 and the traverse-rod independent of the action of the cam. This extra throw maybe increased by adjusting the screw-stud 6 higher on the bracket e.

The eccentric c is a cam, the term eccentric being used to distinguish the same from the cam c.

The continuous changes in the length of the traverse as well as the speed secure an IOC even wearing of the drawing and top rolls and increase their durability.

Having thus described my invention, 1 claim as neW and desire to secure by Letters Patent- 1. A traverse motion for spinning machines, consisting in the combination of a pair of gears differing in the number of their teeth, and each having a cam connected therewith and driven thereby, a suitable gear for driving said 'difierential gears, an oscillating lever rocking on a stationary fulcrum intermediate its ends, one end of said lever being acted upon by one of said cams to oscillate the lever, an arm pivoted to the other end of said lever so as to be swung thereby and acted upon by the other said cam to oscillate said arm, and a traverse-rod mounted on said swinging arm, substantially as and for the purpose set forth.

2. A traversemotion for spinningniachines, consisting in the combination of a pair of gears differingin the number of their teeth, a suitable gear for driving said differential gears, a fixed stud and a sleeve turning thereon, said sleeve being provided with a cam and having one of said differential gears fast on said sleeve, the other said gear being loose on said sleeve and provided with a cam, an oscillating lever acted upon by the cam controlled by said loose gear, a swinging arm pivoted to said oscillating lever and acted upon by the cam controlled by said fast gear, and a traverse-rod mounted upon said swinging arm, substantially as and for the purpose set forth.

3. A traversemotion for spinningmachines, consistingin the combination of apair of gears differing in the number of their teeth,

a set of drawing-rolls having the back one thereof provided with a driving-worm for actuating the said differential gears, a fixed stud and a sleeve turning thereon, said sleeve being provided With a cam and having one of said differential gears fast on said sleeve, the other said gear being loose on said sleeve and provided with a cam, an oscillating lever acted upon by the cam controlled by said loose gear, a swinging arm pivoted to said oscillating lever and acted upon by the cam controlled by said fast gear, and a traverse-rod mounted upon saidswinging arm, substantially as and for the purpose set forth.

4. A traverse-motion for spinningmachines, consisting in the combination of asupport a provided with a fixed stud a, a loose sleeve a mounted upon said stud and provided with a cam c, a pair of differential gears c and 0 the former mounted fast upon said sleeve and the latter mounted loosely thereon and provided with a cam 0 the said pair of gears simultaneously driven by the same means, an oscillating lever d rocking upon a pivot a and having its upper end engaged by the said cam 0 so as to oscillate the lever upon its pivot, a swinging arm 6 pivoted to the lower end of said lever d, and having its upper end engaged and actuated by the said cam c for swinging it upon its pivot, and a traverse-rod carried by said swinging arm, subtantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

OSCAR L. OWEN.
